T3 Terminator muzzle brakes are designed for .223 to 338 Magnum cartridges on barrels up to 25mm diameter.
The T3 doesn’t have a top or bottom, it has flats for a 23mm, 15/16 spanner and a small indexing mark so they can easily be fitted by a Gunsmith.
Ports are 90 degrees to the ground to minimise debris disturbance
The ports are angled back away from the shooter to minimise shooter discomfort and maximise performance.
The standard through holes are for .264 & .308 calibres
It requires opening up to 0.025-0.030″ over bore size when fitted to larger calibres.
It is recommended the rear of the brake be tapered down to the muzzle diameter.
The T3 is 25mm, 0.984” diameter, 69mm, 2.72” long & weighs 85-115 grams, 2.99-4.05 oz depending on thread.
